MADP-007436-1146DT

RF Diode Overview

The MADP-007436-1146DT is a silicon PIN diode configured as a Series Tee Reverse (STR) within the MACOM SMPP series. It utilizes the SOT-323/SC-70 (Case Style 1146) surface mount plastic package. The device features an intrinsic region thickness of 0.4 mils and a nominal minority carrier lifetime of 0.2 µs. Key electrical specifications include a maximum reverse voltage of 75 V, a total capacitance of 1.00 pF measured at 20 V, and a maximum series resistance of 0.5 Ω at 10 mA forward bias current.

RF Diode Feature Summary

• Series Tee Reverse configuration for microwave control circuits
• Low series resistance optimized for low loss switching applications
• Lead-free surface mount construction with matte tin plating
• RoHS compliant plastic packaging

RF Diode Applications

• Low loss series switches
• High isolation shunt switches
• Microwave control circuits

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm the STR configuration and Case 1146 package style. Ensure compatibility with standard reflow soldering profiles that do not exceed +250°C body temperature. Confirm RoHS compliance requirements match the manufacturing revision. Validate pinout orientation against the schematic design before assembly.

RF Diode Selection Notes

Select this component when low on-state resistance is critical for minimizing insertion loss in series switch topologies. The 0.4 mil I-region provides a balance between low resistance and moderate capacitance suitable for frequencies up to 3 GHz. Consider the Series Tee Reverse layout if circuit board space or trace routing requires this specific internal connection topology.

RF Diode Part Context

This part belongs to the MADP-007436 series, which is characterized by the lowest series resistance in the SMPP portfolio. It shares the same semiconductor structure as the MA4P7436 but is housed in the SC-70 (1146) package variant. The STR designation indicates a common cathode arrangement with specific terminal assignments distinct from single or common anode configurations.
